Centrifugal particle accumulator

Abstract

An apparatus can include a first curved blade for use in a centrifuge. The centrifuge can be for collecting debris particles in a fluid flowing through the centrifuge. The first curved blade can include a plurality of eccentric slots. The first curved blade can include a groove positioned at an outer edge of the curved blade. The first curved blade can also include a first mating element and a second mating element. The first and second mating elements can be for coupling the first curved blade to a second curved blade about a central axis.

What is claimed is: 
     
       1. An apparatus comprising:
 a first curved blade for use in a centrifuge positionable within a wellbore for collecting debris particles in a fluid flowing through the centrifuge, the first curved blade comprising:
 a plurality of slots; 
 a groove positioned at an outer edge of the first curved blade; 
 a first mating element sized and shaped to mate with a second mating element on a second curved blade for coupling the first curved blade to the second curved blade; 
 a protrusion on a first surface of the first curved blade; and 
 a recess on a second surface of the first curved blade for coupling the first curved blade on an additional curved blade in a linear direction, the first surface being on an opposite end of the first curved blade from the second surface. 
 
 
     
     
       2. The apparatus of  claim 1 , wherein the second curved blade includes a plurality of slots and a groove positioned at an outer edge of the second curved blade. 
     
     
       3. The apparatus of  claim 2 , where the first curved blade is further coupleable to a third curved blade and a fourth curved blade to form the centrifuge. 
     
     
       4. The apparatus of  claim 1 , wherein a slot of the plurality of eccentric slots intersects with the groove. 
     
     
       5. The apparatus of  claim 1 , wherein a slot of the plurality of slots of the first curved blade intersects with a slot on the additional curved blade.
